AW: multiple power supplies in a modular

[Paul Schreiber]

Transient Voltage Suppression Diode.

Us old farts call them 'Transzorbs' (which was a trademark of the first ones made, around 1980).

Basically, a very fast (<1ns) pair of Zener diodes, use to clamp transients. Expensive (about $1) but works
much better than say a $0.18 MOV (Metal Oxide Varistor, what is used in "Surge Strips" for computers)

I've heard of a metal oxide varistor for overvoltage clamping, but what is
a TVSD?
Thanks! :)

These will clamp any overvoltages.  You might want to try these things on
your supply lines etc.  They seem to be worthwhile.  Definitely have
improved reliabilty of the product.  And I think only ours have
em....(plug)  :-)
